Application filed January 4,1906. Serial No. 294,520.

To all whom it may concern.-

Be it known that I, FREDRIorr J. KOBUSGH, a citizen of the United States, and a resident of St. Louis, Missouri, new and useful Improvements in Heating- Drums, of which the following is a specification containing a full, clear, and exact description, reference being hadto the accomanying drawings, forming a part hereof.

My invention relates to a heating-drum, and is an improvement on the heating-drum patented by me November 14, 1905, No. 804,735.

The object of my invention is to generally have invented certain are removably arranged on improve the construction shown in the pat- 1 ent above referred to and particularly to construct a heating-drum that may be read ily put together without the use of rivets or similar fastening devices.

A further object of my invention is to construct a simple heating-drum that will very effectually radiate the heat from the smoke and products of combustion that pass through the drum.

To the above pur oses my invention consists of certain novel features of construction and arrangement of parts, which will be herefully set forth, ointed out in my claims, and illustrated in t e accompanying drawings, in which a Figure 1 is a vertical section of a heatingdrum constructed in accordance with my invention. Fig. 2 is a perspective view of the I baffle-plates and framework that are located on the interior of the drum. Fig. 3 is a side elevation of one of the legs or frames that support the bafflelates' within the drum. Fig. 4 is a transverse section taken on the line 4 4 of Fig. 1.

Referring by numerals to the accompanying drawings, 1 indicates a cylindrical drum constructed of sheet metal and connected to the members of a vertical line 2 of stovepipe provided with the flaring ends 3. Horizontally disposed within the lower end of the drum 1 is a small sheet-metal cone 4, the a ex of which points upwardly, and formed t rough said cone are the slots 5. Located a short distance above the cone 4 is a conical rin 6, of sheet metal, the diameter of which is s ightly larger than is the diameter of the small cone 4. Formed through this ring 6 at suitable distances apart are slots 7.

Horizontally disposed in the upper end of the drum 1 is a low sheet-metal cone 8, pro vided with suitably-arranged slots 9, and the diameter of this upper cone is somewhat larger than is the diameter of the ring 6.

A series of vertically-arranged frames 10 the interior of the drum 1 and support the two cones and the ring in proper position therein. Each frame is constructed of a thin strip of sheet metal, the lower end of which is formed into a hook 11 and which engages in one of the slots 5 in the lower cone 4. From the edge of said lower cone 4 all of the narrow strips extend outwardly and downwardly to the lower end of the'cylinder 1, and from this point they extend upwardly to a point approximately half-way between the ends of the cylinder 1. At thispoint the strips are doubled, as indicated by 12, and said doubled ortions are extended upwardly and inward y, and the ends of said doubled portions are formed into hooks 13, that engage through the slots 7 in the ring 6. The upper portions of the narrow strips forming t e frames 10 extend u wardly from the doubled portions 12 to t e top of the cylinder 1, and from thence said upper portions are bent downwardly and thence inwardly and upwardly beneath the edge of the upper cone 8, and the ends of said strips are formed into hooks 14, which engage through the slots 9 in the upper cone. There are preferably three of these frames, and as they are constructed of thin sheet metal they are readily bent into proper shape, so as to rigidly hold the two cones and the ring in proper position. Thus said cones and ring, together with the frames, are fixed together without the use of rivets or similar fastening devices, and the entire frame is repdnovably positioned in the drum or cylin- The cones 4 and 8 act as baffle-plates for the smoke and products of combustion that ass through the drum, and the ring 6 tends to deflect the smoke and products of combustion to the center of the drum beneath the cone 8, and thus the smoke and products of combustion are retarded in their passage through the drum, and for this reason the heat from said smoke bustion is radiated from the drum. The soot passing upwardly through the stovepipe and drum will to a large extent be caught by the cones and ring and will be deflected thereby downwardly through the drum and lower ortion of the stovepipe back into the stove and there be consumed.

A heating-drum of my improved construction is simple, strong, and durable, can be I very cheaply manufactured, owing to its simple construction, and the frames and cones can be manufactured and shipped in knockdown form and readily put together without the use of rivets or similar fastening devices.

I claim I 1. The combination with a cylinder, of a series of vertically-arranged frames detachably held within the cylinder, hooks formed integral with said frames, a pair of cones secured to the hooks at the upper and lower ends of the frames, and a conical ring arranged between the cones and secured to the hooks at the centers of the frames substanl tially as specified.

2. An improved heating-drum, constructed with a cylinder, a series of frames vertically disposed within the cylinder, a large cone within and near the upper end of the cylinder and secured to the upper ends of the frames, a small cone in and near the lower end of the cylinder and supported by the lower ends of the frames, and a conical ring arranged between the cones and supported by the central portions of the frames; substantially as speclfied.

3. In a heating-drum, a cylinder, a large imperforate cone concentrically sup orted in the upper end of the cylinder, a sma l imperforate cone supported in the lower end of the cylinder, and a conical ring supported be tween the two cones at the center of the cylinder substantially as specified.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
